Practical C Programming

By: B. M. Harwani

Overview of this book

Used in everything from microcontrollers to operating systems, C is a popular programming language among developers because of its flexibility and versatility. This book helps you get hands-on with various tasks, covering the fundamental as well as complex C programming concepts that are essential for making real-life applications. You’ll start with recipes for arrays, strings, user-defined functions, and pre-processing directives. Once you’re familiar with the basic features, you’ll gradually move on to learning pointers, file handling, concurrency, networking, and inter-process communication (IPC). The book then illustrates how to carry out searching and arrange data using different sorting techniques, before demonstrating the implementation of data structures such as stacks and queues. Later, you’ll learn interesting programming features such as using graphics for drawing and animation, and the application of general-purpose utilities. Finally, the book will take you through advanced concepts such as low-level programming, embedded software, IoT, and security in coding, as well as techniques for improving code performance. By the end of this book, you'll have a clear understanding of C programming, and have the skills you need to develop robust apps.

Introduction to bitwise operators

Every number that we enter into any variable is internally stored in the form of binary digits. To perform bit-level operations, C provides the following bitwise operators.

& (binary AND)

This results in a binary 1 if both the operands are 1. If either of the bits is 0, then the result of the & operation is 0.

Assuming that operand A has a value of 1010 and operand B has a value of 0111, then A&B will be as follows:

A 1010
B 0111
A&B 0010

| (binary OR)

This results in a binary 1 if either of the operands is 1...
